Subject: ffi: rename ptr-in-out to just ptr.

Why have this verbose naming for the most basic case.
Rather, ptr-in and ptr-out are optimizations of ptr which
just avoid copying the object in one direction.

* ffi.c (ptr_in_out_s): Renamed to ptr_s.
(ffi_ptr_in_out_put): Renamed to ffi_ptr_put.
(ffi_type_compile, ffi_init): Follow rename.

* ffi.h (ptr_in_out_s): Declaration updated
